POLE SUPPORT.

Application led December 8, 1923.

To all whom it may concern:

Be it known that we, FRANCIS CUTTLE and HENRY E. DnNYsn, citizens of theUnited States, residing at Riverside, in the county of Riverside andState of California, have invented a. new and useful Pole Support, ofwhich the following is a specification.

This invention relates to sockets to the type employed in the earth forsupporting poles, the principal object of such sockets being to preventor minimize decaying of the lower ends of the poles, the sockets holdingthe poles free from the earth. The term poles is used herein in ageneric sense to define poles of the type employed in supporting wiresabove the surface of the earth, as well as other poles or posts.

An object of the invention is to support the pole in a manner to permitof air circulation and water drain passages to extend in proximity tothe pole so that any moisture that gets into the pole seat will readilydrain therefrom and so that air can freely circu- Y late around the baseof the pole. The construction of the pole seat is such as to support'thepole without the use of gravel or other material that tends to holdmoisture and prevent the free circulation of air.

Another object is to provide a socket of this type in which a pole canbe readily inserted without the necessity of raising the pole to anygreat extent above the surface of the earth. This is especially ofimportance when the pole carries wires or cable. In order to effectthis, the socket is longitudinally divided into sections and means areprovided to secure the sections to one another.

Another object is toprevent water that may rundown the exposed portionof the pole from entering the socket, thus minimizing the tendency todecay of those portions of the pole-that are yin contact with thesocket.

- The accompanying drawings illustrate the invention Figure 1 is alongitudinalv view of a pole socket constructed in accordance with theprovisions of this invention, a fragment of a pole being shown mountedin the socket.

Fig. 2 is a longitudinal view, looking at the inner face of one of thesocket sections,

a fragment of a pole being shown in place in the socket, and the bindingcollars being shown in section.

Figs. 3, 4 and 5 are plan sections on the lines indicated by 3 3, 4 4,and 5 5, respectively, Fig. 1, the pole being omitted in Fig. 3.

Referring to the drawings, there is provided a tubular body, preferablydivided -longitudinally to form a pair of opposed other section. The eyeportions of the members 8 project into longitudinally extending openingsor channels 10 which open to the peripheral face of the tubular member.The channels 10 occur at the joints between the sections, one half ofthe channel being in one section and the other half in the othersection.

Positioned in the channels 10 and inserted through the eyes 9 are boltsor pins 11 which function to hold the sections together. These elementsmay be inserted at the top of the tubular member, since the channels 10open to the upper end of said tubular member.l The upper portion of thebore of the tubular member constitutes a pole seat 12 which ispreferably reduced downwardly, as illustrated. The channels 10 extend tothe seat 12. In order that the wooden post or pole, indicatedfragmentally at a, may be firmly seated in the tubular member, withoutinterfering with the drawing oif of moisture and the circulation of airaround the base of the pole, the bore portion or seat 12 islongitudinally corrugated, the channels of said eorrugationsconstituting drain and air ducts 13 and the pole or post contacting withthe bore 12 at only the rib portions 14 of the corrugations.

The lower portion of the pole 12 will preferably be taperedcomplementarily to the taper of the seat 12. The corrugations are turnedinwardly at their lower ends, as indicated at 15, to form abutments tolimit descent of the pole in the tubular member. The lower ends of theducts 13 communicate with the lower bore portion 16 so that any watergetting into the ducts 13 can readily drain therefrom into the boreportion 16.

In order to utilize the channels as ports for the passage of air to andfrom the ducts 13, there are provided transversely extending air ducts17 which cut through the corrugations and which commimicate at theirends with the channels 10. Thus air can freely circulate through theducts 13 to rapidly evaporate any moisture that may be in said ductsand, especially, between the ribs 14 andi pole, so as to prevent orminimize decay oi said pole.

Though the upper ends of the ducts 13 may be left uncovered, it is ofadvantage to provide a cover 18, preferably formed in 'ralf sections,said cover being in the form ofl a conic rustum and having its smallerdiameter portion concave-convex, as indicated at 19, to tit into anannular groove 20 formed in thepole a. A wire 21 is bound around theconcave-convex portion 19, thus securely holding the sections 18 inplace to shed any water that may run down the pole, and thus preventsaid water from running into. the bore of the tubular member. Preferablythe collar 18 is spaced 'slightly :trom the tubular member so as to forman air passage 22 between the collar and the upper end of the tubularmember, thus still further facilitating circulation of air around thatportion of the pole that is inserted in the socket.r

To install a pole in the socket above described, assuming that the poleis to be removedfrom .the earth and has-wiresattached to it, the polewill be sawed ofi' just above the surface of the earth and the sawedupper part moved to'one side of the portion remaining in the earth. Theearth will be excavated and said remaining portion removed and one ofthe sections 6 will be placed in position in the excavation. Then a barwill be-laid across the excavationsV so as to extend through the channel10. It desired the bar may rest on jacks. The post will then be moved soas to rest on the bar and thepa-cks will be operated to hoist the poleslightly above the position it is to occupy in the socket. Y Y

It will be noted that this may be accomplished'without raising the polemore than a few inches. This is quite an advantage,

especially if the pole is wire-strung, for example, ot the type employedfor carrying telephone or telepraph wires. Then the other socket section6 will be inserted in the excavation, the bolts 11 slipped intovplace inthe eyes 9, and the jacks operated to lower the pole into engagementwith the seat 12. Then the cover 18 will be secured in place.

To further bind the lower portions of sections 6 together, it maysometimes be advisable, especially where the socket is to be subjectedto excessive loads and strains, to employ collars or bands 23 which willbe slipped on over the pole and over the sections 6 after said sectionshave been assembled in position in the excavation and before the polehas been lowered into its seat.

It will be clear from the foregoing that the post or pole is entirelyfree from engagement with any material holding it, excepting at the highpoints oi the ribs of the corrugations, thus there is nothing more thanline contacts'between the socket and the pole. Because there is onlyline contact the wood along the lines of `contact will quickly dry, ifit should happen that moisture is conducted to the surface of the poleby the concrete, thus minimizing lthe liability of decaying of the wood.Ot course the free circulation of air through the ducts 13 and crossducts 17 aids in maintaining the wood in a dry condition.
